Doddridge was a zealous dissenting minister who was actively involved in his clerical duties. He was a prolific sermon writer, usually spoken extemporaneously. He would often follow his sermons with an original hymn, based off of biblical texts and intended to reinforce the day's sermon. These hymns were collected from MS and published posthumously. He also reviewed works by Newton and Hutcheson, in addition to editing the works of literary friends (see 'Periodicals and Misc. column).
